2. UNPACKING AND INSPECTION
Carefully unpack the valve and examine the items contained in the carton.
These will include:
• Valve Assembly
• Valve bracket
• Sample Needle Kit and fluid line
• Valve Air Hose
• User guide
3. DESCRIPTION
The TS5440 Microshot Needle valve is designed to dispense low to medium viscosity material with very
precise deposits over a wide range of shot and bead sizes down to a fraction of a micro liter. An internal
spring return makes the valve fully adaptable for use with Techcon Systems time/pressure controllers. A
short opening stroke provides extremely fast, positive shut- o ff. An external stroke control adjustment
makes it easy for the operator to fine tune shot sizes. The TS5440’s compact design allows for
mounting flexibility and easy integration into automated applications.
4. THEORY OF OPERATION
The TS5440 is a normally closed, adjustable opening, needle and seat valve. Inlet air pressure through
port (1) retracts the needle assembly (2) from the seat inside the dispensing tip (3) allowing material to
flow from the valve material inlet (4) to the dispensing tip (5). Relieving the input air pressure allows
the spring (6) to return the needle back to its position to close the material path.

5. SETUP INSTRUCTIONS
Refer to Figure 3.0
NOTE: This installation uses luer lock adapters shipped with the valve. Any approved material
line with 1/8” NPT connections will work.
1. If desired, mount the valve to the bracket included (1).
2. Connect fluid feed line to valve inlet port (2).
3. Insert the open end of the air hose to air inlet fitting (3) then connect the other end to an
approved valve controller.
4. Set the fluid reservoir pressure. Do not exceed 100 psi (6.9 bars)
5. Install desired dispense tip (4) to the valve outlet and secure it with the retaining ring (5)
NOTE: Recommended dispense tip size is 22-gauge or smaller. Use larger than 22-gauge
dispense tip may results in valve leakage.
6. Make sure all connections are tight
7. Place container under the valve outlet and activate the valve until the fluid flows steady.
The amount of fluid that flows through the valve is determined by:
• Flow control adjustment - Turn end cap counterclockwise to increase material flow rate.
• Length of actuation, set at controller (Valve open time).
• Fluid reservoir pressure
• Dispensing tip size
